Black Satin blackberries are perennial plants which bear thornless upright biennial canes which grow up direct from the roots. In late spring pinkish-white flowers appear on the tips of branches. These are followed in mid-late summer by large black fruit with a sweet flavour – sweeter than thorny varieties.  Black Satin is a vigorous grower that establishes quickly, produces heavy yields, and requires trellising. It tolerates more heat than some other varieties. Plants are self-fertile and pollinated by bees.

Blackberries are hybrids between individual species in the Rubus subgenus Rubus, and also between the subgenera Rubus and Idaeobatus. Confused?! Don’t worry, basically the term blackberry can refer to many related species which hybridise! Wild species are thorny but many thornless varieties have been bred since the 1920s, including this one.

Cultivation

Blackberries can cope with very average or poor soil, but prefer well-drained soil with adequate moisture and levels of organic matter. They can tolerate full sun or part shade and prefer some protection from wind. They will need watering through dry spells.

The stems or canes go through a two year cycle. In the first year, a new stem, the ‘primocane’, reaches a height of 1.5 metres or more and produces leaves but not flowers. In late summer – early autumn, prune off 10cm of the terminal growth of the canes to help initiate the production of fruiting spurs the next year. In the second year, this cane is a known as a ‘floricane’, and the lateral buds open to produce flowering laterals.  After these canes have fruited they should be pruned off right from the base, in autumn or winter.  All strong canes produced in spring and summer should be tied up, and thin, weak canes, or ones heading into your pathways should be pruned off.

Uses

Blackberries are well known for their delicious juicy fruit which can be eaten fresh, used in various desserts, or used to make jams, jelly, wine etc.

Blackberry fruit, leaves, and stems have been used to dye fabrics and hair. Native Americans used the stems to make rope.

Medicinal Uses

Blackberries have been used medicinally by many cultures, including the Greeks, Northern Europeans and Native Americans.  Blackberry leaf contains tannins which can soothe the gut and treat diarrhoea and mild inflammation.  The astringent, anti-inflammatory and antibacterial effects make it ideal for sore throats, oral thrush, mouth ulcers, and bleeding gums. They can also help reduce heavy menstrual flow and ease cramping, and treat skin conditions such as eczema, psoriasis, and acne. Blackberry root has a stronger astringent effect than the leaves.

Both berries and leaves are rich in vitamin C and antioxidants that support the immune system and reduce inflammation. The berries are also rich in polyphenols, which may have antiviral properties.

Blackberries contain numerous seeds which are rich in omega-3 and omega-6 fatty acids.

Primary Actions:  astringent, anti-inflammatory, antibacterial, antiviral, antioxidant

Parts Used: leaf, root, berry

History / Folklore / Further Info

Botanically speaking blackberries are not actually berries but aggregate fruits, composed of small drupelets, each containing a seed. Each drupelet is attached to the receptacle – the central axis of the blackberry fruit which holds the fruitlets together as they develop. When you pick a blackberry, the receptacle stays in the fruit, whereas when you pick a raspberry, the receptacle remains on the vine, and the raspberry fruit has a hollow core. Just in case you ever wondered why – and now you know!

According to British and Irish folklore, blackberries should not be picked after Old Michaelmas Day (11 October) as the devil or spirit may have stepped, spat or fouled on them – perhaps a warning of the moulds which can infect the berries in damp autumn weather.

Jo Says

Growing up in England, dog walking in woodland or along our local canal tow path in late summer was always accompanied by multiple stops to pick blackberries. One in the mouth, one in the bag, and finally enough to take home to freeze! Both my grandmothers had Bramley apple trees in their back gardens, and the resulting apple and blackberry crumbles were always delicious!
